Figures & data
Figure 1. Age-standardized mortality of middle-aged men from coronary heart disease by province in Finland, 1971–1975 Citation20 (upper figures) and 1997–2003 (lower figures) Citation32. The mean value for the entire male population of Finland is 100. Diagram shows average population by western and eastern birthplace among male residents of Helsinki Citation18 and out-of-hospital deaths in the Helsinki Sudden Death Study series during 1981–1982 and 1991–1992.
Table I. Characteristics of the study population. Values are means±SD for normally distributed continuous variables, and numbers of cases (percentages) for categorical variables.
Figure 2. Frequency distribution and multivariate birthplace-based risk (odds ratio (OR) and 95% CI; above bars) for prehospital sudden cardiac death due to coronary heart disease including information on all myocardial infarction (acute or old) and coronary thrombosis among ≤54-year-old (upper figure) and >54-year-old men (lower figure) born in east and west Finland in the Helsinki Sudden Death Study series during 1981–1982 and 1991–1992.
Table II. Risk for prehospital sudden cardiac death (SCD) due to coronary heart disease (CHD) associated with birthplace with and without CHD risk factors in men aged 35–69 years in metropolitan Helsinki. Values are means for normal distributed continuous variables, percentages for categorical variables and odds ratio (95% CI) for risk for SCD due to CHD (codes I20–I25).
